“…The proportion of epistemics is substantially lower than in the corpus studies on adult speech mentioned in the introduction (Ruppenhofer & Rehbein, 2012, Rubinstein et al, 2013, Marasović et al, 2016, see also Coates, 1983, Klages & Römer, 2002, Hacquard & Wellwood, 2012, Baker et al, 2012. For some of these studies, the difference might be due to the fact that they involve written language (Coates, 1983 andHaan, 2011 show that modal use differs substantially in written vs. spoken language). But even studies on spoken adult language show a higher proportion of epistemics: in the MASC corpus of American English, Marasović et al (2016) find 26% epistemics in almost 2,000 functional modals (n = 508, their Table 5, p.17).…”
